How to Buy the Perfect PC
By Dee Kerr
PCs have become a staple in every
home. Without PCs, you will find it hard to stay connected and to even do
the work required of you in school or in the office. With so much PC
packages being shoved to our throat every time we go to department stores
and computer shops, you'll really get quite confused on what you really
need and what PC package will fit your budget and lifestyle. To help you
through this dilemma, here is a brief backgrounder of the parts of PCs
that you should get to know.
Processor.
This is one of the three primary components of your PC. The processor is
the part that determines how fast your computer process information. Intel
is still the leading brand in processors but competitors such as American
Micro Devices (AMD) are slowly catching up, offering cheaper alternative.
In shopping for a processor, one should consider the following:
Clock speed - this will show the number of instructions that a computer
can execute in a second. This usually comes after the brand name.
Processors nowadays are already set at the gigahertz range.
Cache memory - this stores the data that were previously accessed. This
simplifies the work of the computer as it would not take twice as long to
access information already stored in memory bank. Without a cache memory,
much of the work will fall on the RAM (Random Access Memory).
Operating temperature - some processors easily heats up. Before buying,
make sure that you have asked about the operating temperature just in case
you need to buy additional fans or put the computer in an air-conditioned
room.
RAM (Random Access Memory)
RAM serves as the temporary memory of the PC, containing information that
are needed for the computer and the programs to function. In addition to
processors, RAM also determines the speed of the computer. The higher the
RAM, the faster the computer is in accessing information and responding to
commands.
Motherboard
This is where all the parts of the PC's CPU (Central Processing Unit) are
attached. Some motherboards already have videocards and soundcards
embedded on it while others don't. what is important however is to choose
a motherboard that is compatible with your RAM and processor.
Incompatibility of PC hardware can cause major problems and may even lead
to the breakdown of your computer.
Hard drive
This is the part where you store all the information in your PC. Picture a
floppy disk with much much larger storing capacity. The hard drive serves
as the permanent memory of your computer. Here you install all your
programs and save all the documents that you need. It is also important
that you buy a hard drive with really big capacity especially now when
people are so used to storing multimedia files that may use up a lot of
hard drive space.
Video cards
This is the part of the computer which determines the quality of the
multimedia images that you will view. The higher the memory of the video
card, the better is the picture quality and the colors. Also, video cards
are also responsible for how fast multimedia images are accessed. This is
especially needed if you use your computer for multimedia activities such
as watching a movie or playing video games.
